Astarita told state police investigators that he was among the agents at the roadblock and described how Finicum's truck approached at about 70 mph. Astarita said he believed Finicum had struck another hostage team agent as he swerved into the snowbank.
That could explain why he took the shot, but doesn't excuse lying about it.
There’s a documentary called “American standoff” show video from inside the truck as well as overhead video.
They truck wasn’t ongoing 70 mph, more like 30 mph, when it hit the snowbank. They shot at the vehicle soon after it stopped moving. Lavoy exited the truck as instructed, then it appears his was shot from behind.
